Hi cmagee1982
I think I can see your tree on a/try here
http://trees.ancestry.co.uk/tree/33976074/person/28134575067?ssrc= There is also one further tree, likely a relative of yours as you both show Margaret born c. 1904 as grandmother.
You both seem to have good detail I think coming forward, it is the going back that is the problem. One of the reasons may be that Margaret's parents didn't marry until 1913. Alexander a widower, Maggie a spinster...this might be why they had to wait to marry until 1913? Waiting for Alexander's wife to pass before they could legally marry? This means that daughter Margaret's birth may likely show under her mother's maiden surname. Seems you may have this to find too...
The marriage I found was this one:
1913 Alexander MCDONALD and Maggie MCGILVRAY in ANDERSTON - GLASGOW CITY/LANARK 644/11 0289
Alexander's occupation matches that which shows on the image you have for daughter's marriage, dock labourer.
Alexander's age in 1913 showing as 56, so born c. 1857ish (that can vary as you know until you find better details). May also have been born before the start of official registration in Scotland, which will make it harder to find details. I can't see his birth easily (or siblings) on the index on
https://familysearch.org/search as a guide. Parents a James McDonald, cab drive and Ann Ree (likely also Rae/Rea and variants). Both Deceased.
No luck yet on finding a birth entry for Maggie McGilvray, a spinster aged 41 at marriage. Parents a John McG and a Catherine McDonald. Both Deceased.
Maybe check for your grandmother Margaret's parents' deaths. Their death certs might give some other details to help you verify info. Your grandmother married twice? This will help you possibly narrow down death dates for her parents if they showed as deceased by the time of her second marriage.
